Lyla appears to be getting into her groove. Today, she just walked right on up the stairs without even asking me to come up to the classroom. Yesterday, she told me she wanted me to leave her in the classroom, but today was fine heading up on her own.
One of the teachers told me that yesterday, once Lyla was sitting down on the carpet, she looked around, realized no one else was crying and calmed down and stopped crying. After that, the rest of the day was totally fine.
Here's hoping I'm done with the pre pre-school tears!
